David White, the chairman of NZ Cricket, told a press conference this morning that matches involving Vincent’s domestic team, the Auckland Aces, are being probed by anti-corruption officers.

“We can confirm the following: No games played in New Zealand are being investigated by the ICC; no current Black Caps are being investigated," White said.

"No matches involving New Zealand national teams are being investigated, however, we have been informed by the ICC that some Auckland Aces matches in the Champions League in South Africa in 2012 are being investigated.”

Telegraph Sport also revealed that one current international captain had been asked to fix and turned down the offer, reporting the approach to anti-corruption authorities immediately.

White declined to comment when asked if McCullum was the player in question. “Sorry I cannot say anymore as it could jeopardise further investigations.” When pressed further on McCullum he answered: “Sorry I can’t say.”

One of the matches Auckland played in the Champions League in 2012 was against Hampshire although it is not known at this stage which games are under suspicion.

Vincent is understood to have also provided details of fixes, or attempted fixes, in England, Hong Kong, India and South Africa.

Vincent is being investigated along with Chris Cairns and Daryl Tuffey, former team-mates for New Zealand as well as for the Chandigarh Lions in the Indian Cricket League. Cairns successfully sued Lalit Modi for libel in 2012 over allegations of fixing in the ICL. Modi had to pay more than £2 million in costs and damages.

Earlier this year Cairns’ barrister, Andrew Fitch-Holland, was arrested on suspicion of perverting the course of justice in relation to the Modi libel trial. He was interviewed again by Scotland Yard detectives on Wednesday and bailed to appear again in August or September.

Cairns has also been interviewed by the Metropolitan Police and told the New Zealand Herald: “I'm waiting to conclude the interview I started with the Met over six weeks ago here in New Zealand. Obviously the time it's taken to conclude this is frustrating but I continue to cooperate fully with the relevant authorities. Regarding Lou Vincent's comments and the position of Andrew Fitch-Holland, I maintain my stance that I do not comment on other people's situations in this matter.”
